emulsion
의미: A stable mixture of two normally immiscible liquids, such as oil and water, achieved through the use of an emulsifying agent; in British English, commonly used to refer to a type of water-based interior paint.
Emulsions are ubiquitous in food science (mayonnaise, vinaigrettes, homogenised milk), cosmetics (creams, lotions), pharmaceuticals, and industry. An emulsifier — such as lecithin in food or surfactants in cosmetics — stabilises the mixture by reducing the surface tension between the two phases. In British everyday usage, 'emulsion' typically means emulsion paint, a water-based wall paint that is easy to apply and dries quickly. 'Oil-in-water' and 'water-in-oil' describe the two main types of emulsion, depending on which liquid forms the dispersed phase.
